Know ALL MEN BY THESE PRESENTS:

That I, GEORGE ROWE, of the city and county of Worcester, andCommonwealth of Massachusetts, have have made certain new and usefulimprovements in 'PinfToolsg and I do hereby declare that the followingis a. full, clear, and exact description of the same, reference beinghad to the accompanying drawings, forming a vpart of this specication,in Which- Figure l represents a perspective view of my improvedpimtool.

Figure 2 represents a longitudinal central section.

Figure 3 represents a perspective view of the cuttingpart; and

Figure 4 represents a longitudinalY section of the (slitting and holdingparts, and the key by which they are separated. 1

This tool is designed to facilitate the `splitting or cutting out ofwooden pins from blocks of wood to be .used in the manufacture ofwindow-sash, blinds, and for variousother purposes.

In the drawings, the part marked A represents the main part of thepin-tool. The lpart marked A is made hollow, as shown at B, and theupper end C is turned round, and also tapering. The lower end D is boredor rea'med out to receive the upper end a of the removable part E of thepin-tool, which is also made slightly tapering to vfit vthe hole'in theend D, as fully indicated in the drawings. The upperinner surface of Eis recessedback, as shown at b. A slot or hole, e, is made through thepart D, through which a key, F, is inserted to drive out or separate thepart E from the part A.

The operation of the tool'is as follows: The opera-tor takes the tooland inserts Vthe tapering end Cinto the spindle of .a foot, or oth-ermortisin'g machine, and then places Athe block of wood from which thepins are to be split or cut upon the table of the machine, when, at eachstroke of the chisel arbor, a pin is. split or cut from the block by thepart E. At the next stroke of the arbor a second pin is cut or splitfrpmitlie block, the first pinbeing forced up through the part E by thesecond suciently high to allow of its falling out of the opening G inthe part A. The operation is continued in the same manner'until thedesired number of pins of that size has been made. In case alot of pinsof a diiereut size are wanted,'then Vthe partE is separated from thepart A,as before described, and another point, E, is substituted in lieuthereof. The upper part of E, for anysized pin, is uiade'of the samesize, so that theywill all fit the hole in the end D; but the holes inthe diierent points E are made of different sizes. This is illustratedin the drawings, where, in fig. 4, the-part E is shown with a smallerhole than'what is shown in the corresponding part, iig. 2. In this wayall that is necess ary to do in'order to split or out out pins ofdifferent sizes is to insert a di'erent part E, which has a hole of thesize of the pin desired.4 Y I v As heretofore constructed the pin-toolhas been made in a single piece, the manufacturer requiring'as manydiierent pin-tools as hedesired'to make di'ereut-sized pins. When' made4according to the old'fdan,- if the cutting-point happenedto get broke'or injured the entire pin-tool had to be thrown away. Bymy improvementsthis objection is overcome, besides making a great saving in the firstcost of the article. i I

Havingdscribed my improved pin-tool, what I claim as new and of myinvention, and desire to secure by Letters Patent, as an'irnprovdarticle of manufacture, is i The combination with theremovable punchorcutter E ofthe hollow stein or handle A, slotted as described, so as tofacilitate the withdrawal of the'pins and the removal of the punch, andotherwise constructed and arranged for operation as herein set forth; i.V l
